--- Comment #3 from Martin Wildam <mwil...@gmail.com> 2012-10-24 20:33:10 --- >From current point of view I think it has to do with ambient light sensor. I examined BIOS and there is are two settings: For brightness on AC and for brightness on battery - in both cases it says "if ambient light sensor is off" Sometimes I get those settings without brightness controls working. It looks like that in bright light the controls work but when it's quite dark, they do not and then the brightness controls are not working. Unfortunately I don't have an idea, where the sensor exactly is so that I can test it by putting my finger on it or hold a flashlight onto it. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Everyone hates slow websites.
